1 What is the difference between horizontal installation of the guide rail and vertical installation

Linear guides

In the installation without laterally positioned assembly surfaces, the parallelism between the driven side slide and the datum side slide is ensured.

One. Use the mounting plane mounting method.

First, use the assembly screw to fix the bottom datum of the linear guide rail approximately on the assembling surface of the bottom of the bed, and then use a vise to force the side datum of the slide rail to the side assembly surface of the bed, so as to determine the position of the slide rail, use a torque wrench, and a certain torque force locks the fixing screw in order, and the bottom datum of the slide rail is pressed to the bottom assembly surface of the bed.

Two. Installation of linear guides on the driven side.

1.Straight line block gauge.

Place the linear block gauge between the two linear guide rails, use the micrometer to calibrate the linear block gauge so that it is parallel to the side datum plane of the datum side slide rail, and then calibrate the driven side slide rail according to the linear block gauge, calibrate from one end of the moving rail and lock the assembly screws with a specific torque in sequence.

2.Mobile Platform Act.

Two sliders on the datum side are fixed on a measuring platform, and only one slider is installed on the driven side, and the slide rail and the slider have not been fixed on the bed and the platform, use the thousand-point gauge attached to the top surface of the driven side slider to measure the side datum of the driven side slider, and one end of the driven linear guide rail begins to calibrate and lock the assembly screw with a specific torque in sequence.

3.Follow the datum side slide method.

The two sliders of the datum side linear guide rail and one of the driven side guide rails are fixed on the platform, and then the slide rail of the driven side and the other slide rail are roughly fixed on the bed platform and the platform respectively, and the datum side slide rail is the standard to move the platform, starting from one end of the slide rail, while confirming the rolling resistance of the linear guide rail on the driven side, the assembly screw is locked with a specific torque in order.

4.Special Tool Law.

Use a specialized tool to determine the position of the driven side rails and sequentially lock the mounting screws with a specific torque.

V-rail

The guide rail is the part with the longest life and the least damage in the whole process, and the main function is still the four V-shaped rollers. In the event of damage to the V-roller, the V-roller can be replaced.

Judging by the load-bearing situation, the way it is installed is judged. Take carrying 1 ton weight as an example: when a V-rail rack and pinion drive system needs to carry a weight of 1 ton, we have to choose according to its installation method.

If it is installed on a flat ground, and the four V-rollers work parallel to the ground, then the weight of the four wheels can be evenly distributed by 1 ton. then the load bearing of each wheel is tons. Then according to the selection table, we can choose 25 types.

If it is installed vertically, then it will have to be calculated separately, in this case, only two wheels carry weight, so each wheel carries a ton of weight. According to the selection table, we are going to choose the 35 type.

When selecting the horizontal installation and vertical installation of the guide rail, the following differences are mainly considered:

Bearing capacity: The horizontally installed guide rail mainly bears the force in the horizontal direction, while the vertically installed guide rail mainly bears the force in the vertical direction. Therefore, it is necessary to select the appropriate guide rail according to the actual application scenario and the load to be carried when selecting the model.

Coefficient of friction: The coefficient of friction of the guide rail has an impact on its motion performance and service life. When installed horizontally, the friction between the guide rail and the slider mainly occurs between the contact surface of the slider and the guide rail; In vertical installation, due to gravity, friction occurs not only on the contact surface, but also between the internal structure of the slide and the guide rail.

Therefore, it is necessary to select the appropriate guide rail according to the actual use conditions and friction coefficient requirements.

Installation space: The installation space required for horizontal installation and vertical installation is different, and it is necessary to consider the actual installation location and space size, and choose the appropriate length and size of the guide rail.

Brand reputation: Choose products from well-known brands, such as Sisco linear guide and Mark linear guide, etc., which can ensure the reliability of quality and service. These brands have a wide range of application experience and a good reputation, and are able to provide rail products that meet different needs.

In short, factors such as load capacity, coefficient of friction, installation space and brand reputation need to be considered when selecting the horizontal and vertical installation of the rails. Selecting the appropriate guide rail according to the actual application scenario and needs can ensure the stability and reliability of the equipment. In the process of selection, it is recommended that users refer to the product specifications and technical information provided by the manufacturer in order to better meet the actual needs.

Linear guidesExamples of installation and straightening The linear guide is long and the working stroke is reachable.

The guide rail table is equipped with two rolling linear guide rails, and there are two sliders on each guide rail to ensure the stability of movement.

Two goals of straightening: one.

The straightness of the reference rail.

The error is within the specified range;

Two. The parallelism error between the two guide rails reaches the specified value.

Auxiliary tool: dial indicator with magnetic base.

and spirit level (2um 200mm) coordinate system.

The settings are shown in the figure below: the datum is on the left, the rail to be measured is on the right, the top view from top to bottom is the top view of the measuring system, and the forward view is the main view of the measuring system.

According to the habit of using the coordinate system, the direction shown in the top view diagram of the system is the positive direction of the x-axis direction (horizontal).

On the weights line, set the upward direction shown in the main view to the positive direction of the y-axis (weight).

Rail Datum X-axis positive direction Baseline system top view Figure 1 System top view Baseline rail Datum Y-axis positive system main view Figure 2 System main view There are two kinds of installation, when the CCD is installed.

, the calculation results given by the measurement system are consistent with the actual situation.

If it is installed in reverse, the result is opposite to the actual direction, and special attention should be paid when trimming the straightness of the guide rail.

The more practical installation methods of linear guide rails are:

1. Before installing the linear guide, the burrs, dirt and surface scars of the mechanical mounting surface must be removed.

2. Gently place the main rail on the bed, and use lateral fixing screws or other fixing fixtures to gently fit the linear rail and the lateral mounting surface.

3. Tighten the positioning screws of the slide rail slightly in order from ** to the two-liter rental side, so that the track and the vertical mounting surface are slightly fitted. The sequence is from the ** position to the two ends of the tightening, you can get a more stable accuracy. After the vertical datum plane is slightly rotated and tightened, the locking force of the lateral datum is strengthened, so that the main rail can be properly attached to the lateral datum.

4. Use a torque wrench to slowly tighten the positioning screws of the slide rail according to the locking torque of various materials.

5. Use the same installation method to install the auxiliary rail, and install the noisy and filial piety slide to the main rail and the auxiliary rail individually.

6. Gently place the mobile platform on the slide of the main rail and the auxiliary rail.

7. Lock the lateral pressing screws on the moving platform, and the installation and positioning will be carried out in the following order.

When designing vertical rails, which material is best to use?

Kiss! Hello, happy to answer your <>

When designing vertical guide rails, it is best to use cast iron, steel, non-ferrous metals, plastic (plastic soft belts, composite guide rail plates) cast iron (zhù tiě), iron with high carbon content, brittle, can not be forged, and is used to make steel or cast utensils. A general term for an alloy of cast iron, which is mainly composed of iron, carbon, and silicon. In these alloys, the amount of carbon is greater than what can be retained in the austenitic solid solution at eutectic temperature.

Iron-carbon alloy with a carbon content of more than 2%. Industrial cast iron generally has a carbon content of: Carbon is mostly found in graphite form in cast iron, and sometimes in cementite form.

In addition to carbon, cast iron also contains 1% 3% silicon, as well as elements such as manganese, phosphorus, and sulfur. Alloy cast iron also contains elements such as nickel, chromium, molybdenum, aluminum, copper, boron, vanadium, etc. Carbon and silicon are the main elements affecting the microstructure and properties of cast iron.

Cast iron can be divided into: gray cast iron. The carbon content is high (, the carbon mainly exists in the form of flake graphite, and the fracture is gray, referred to as gray iron.

The melting point is low (1145 1250), the shrinkage is small when solidified, the compressive strength and hardness are close to carbon steel, and the shock absorption is good. Due to the presence of flake graphite, it has good wear resistance. The casting performance and cutting processing are better.

It is used to manufacture machine tool beds, cylinders, boxes and other structural parts. The grade number is followed by "HT" with two sets of numbers. Example rounds, such as:

HT20-40 (the first number indicates the minimum tensile strength, and the second group of numbers indicates the minimum flexural strength). Hope mine can help you <>

Do you have any other questions?

Generally speaking, the larger the format, the worse the flatness, and also depends on the accuracy requirements and the processing level of the equipment.

The parallelism of the linear guide rail is mainly affected by the distance between the two guide rails, which needs to be confirmed by a micrometer meter, and the general accuracy requirements are within the limit, and there are differences according to the use requirements.
